Currently the most common way to talk to someone through WhatsApp is to save their number in our contacts and then go to the application and start a chat. This option is undoubtedly a bit cumbersome, especially when we want to send a message to a person that we do not want to save their number, although that will change very soon.
And it is that a few months ago the news came out that WhatsApp was working on the generation of QR codes to be able to talk to users on the platform without having to do the whole process that we explained above.
As WABetaInfo mentions, when a user generates their QR code, they can share it with anyone, and the others will only have to scan it to start a conversation with that person.
The source mentions that this function is already available in the beta version of iOS and that it will also arrive in the beta version of Android soon, so its launch worldwide could take place in a few weeks.
How are QR codes generated?
WABetaInfo reveals that the QR code is generated from the option in the settings, and a single QR code is created for our account that we can share by the application itself or on other platforms, however, it is necessary to scan from WhatsApp for it to work.
So easily and quickly we can start a conversation with a new user through a QR code, the bad thing is that there may be people who share our code so that other people send us WhatsApp messages, however, if this happens on code can be deleted and a new one can be generated, so if you are going to give your QR code to a user that you do not trust, it is recommended to delete the code after he uses it.
Unfortunately this does not solve one of the privacy issues that has been asked to WhatsApp for a long time, and that is that there are people with whom we can talk, but without them knowing our phone number, as in Telegram.
It was thought that maybe QR codes would fix this, but when someone scans your code and starts a chat then they can see your phone number.
We will give you more detail about the operation of these QR codes when we can try it, while that happens to remember that you can create a chat with someone that you do not want to add to your contact list easily and quickly, and we explain them here.
